Question

Assume that the reservoir is 200m deep, held back by the dam wall . A small horizontal pipe at the base of the dam transfers water to the generator hall, where it gushes out at high speed and is used to turn the turbines that generate electricity.
Bernoulli's equation says that an incompressible fluid like water can contain several different types of energy. Give the main types of energy associated with the water at each point in the hydroelectric system.
1. Why can I ignore air pressure in this system?
2. Main type (s) of energy at the bottom of the reservoir-PPE, KE, GPE, Part GPE and Part PPE or Part KE and Part PPE
3. Main types of energy halfway between surface and bottom of reservoir? Same choices as in 2
4. Main type (s) of energy at surface of the reservoir?
5. Main type (s) of energy at exit of pipe in turbine hall.
What is the speed of the water coming out of the pipe in the generator hall?
